Application tiled March 9, 19009.' Serial No. 482,214.

To all whom it may concern:

Be it known that l.' ARTHUR J. Honor., a citizen of the United States,residing at lasadena, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements inPrinting-Presses, of which the following is a specification.

This inventionrelates to a press of a gen. eral character and operationshown and de scribed in Patents Nos. 867,634 and 872,108 issued to TheMills Automatic Press Company on Oct. 8th, 1907 and November 26th, 1907;andy it consists in generalvimprovements in the mode of operation of thedifferent parts and in the construction of the same to make a moreeflicient press. In the latter mentioned patent, which is the basis ofthe former, a small printing cylinder is utilized, the paperbeing heldon the cylinder by suction after being fed thereto by an appropriatefeeding means. At the end of the printing operation the suction isreleased and the paper passes to a collection box 'over a ldeliveryapron. The Cylinder is solid in its peripheral portions and is of such asize that it Willaccommodate around its circumferencel the largest sizedsheet to -pbc printed. In order to keep the type in the form box fromcontacting with the' cylinder except when it is desired to printupon thesheet of paper, a mechanism is employed to lower the box duringall but asmall portion of its movement, this portion being on the up stroke ofthe type When the; type has-v reached a position adjacent the`cylinderwhich at this time has a sheet of the clean paper around it. In thisform of press the cylinder rotates during all the timethat the form boxon the bed is moving.

.ln the present invention 1t is that the bed and the form box shallreciprocate in a single plane. rather than move in one directizm in oneplane and in the other direction in another plane. After being onceadjusted so 'that the type bears against the cylinder with the correct'pressure the type moves in a simple motion of reciprocation.'lhisinoti'm is supplied by .the same means as in the above mentionedpatentsbut it will be obvious that it maybe supplied in any approvedmanner. ln the present n1a` (chine the cylinder does not rotate `all thetime but remainsat rest during the mot-ion of thle bed in oneldirection,which I may call tie arranged feeding and inking motion of the` formsuction the edge ofthe sheet for its' removal. When of the machine.

.cross section taken on line 5 5 of Thus alternate quarters of theperiphery of the cylinder are cut away and the operation of the wholemechanism is so arranged that when the bed travels back on its inking.movement and the cylinder is stationary one or the other of these cutaway portions is over the. type 4in the form box. In this man# ner it isprovided that the type does not come into contact With thevcylinder orwith any part thereof except when it is desired to print upon the sheetheld upon and supported by the cylinder. Upon the back or in'kingmovement .of the bed and the type in the form box thereon, the feedingmechanism lof the press is arranged and timed to deliver a sheetof paperto the stationary cylinder. This feeding mechanism may be of anypreferred form, the construction illustrated being' the one now in useon the press shown.4 Although it does not enter into thepresentinvention in its particular formflt is included in the showing sothat be complete. In the .present means are employed to engage the samemay clear of the pile the sheetv is l dropped into the feed box lof themachine where it is registered'or alinedl accurately just before beingvplacedon the cylinder.' p

In the drawings designates the frame of the Fmachine which is rovidedwith ways 31 for the support of bed) box 33 therein. In the present formthe bed plate is shown as being supported on an ineline but this is notnecessary to the etlicient working of the press. In the lower-part ofvthe frame-is. ournaled a` main shaft 34 carrying a crank 35 which isconnected through a connecting rod 3G toa bracket 37 secured to theunder` side of the bed plate. The throw of this crank is such that thetravel of the bed plate and the type thereon is just suflicient for theoperations to vbe hereinafter described. The main shaft isldriventhrough the agency of a counter shaft 38 to which itis connected bygears 39.,v The counter shaft is providedvvith' a driving pulley 4.0 andla clutch-41 for connecting it to the shaft, the clutchand also a brake42 being operated by a foot'lever 43 mounted on' the opposite side ofthe machineand operatv 'ing through a shaft 44. 4By this mechanism theoperation of the press may be controlled. Located on the frame at theupper part thereof-,and in proper .relation to .the bed plate, is a .setof inkmg feeders and rolls 45.

As this arrangement is of ordinary construction and has no bearing on'the present invention it will suffice to say that thefaee of the typein the form box is .inked upon its passage under rolls 46 at the upperend of the stroke. y i l The feeding mechanisms-The sheets are placedina pile on a tray 50 and the 'mechani'sm 1s arranged to feed thelowermost sheet( from the pile into chute 92. The for* ward edge ofthelowermost sheet'is bent down by appropriate action of suction apron F55,a valve 114 controlling the suction supply. Fingers 81 then enter4 thepile above the lower sheet and remove that sheet upon their outwardmovement, the fingers being hollon7 with suction ports at their ends forengagement with the sheet. The fingers are mounted on a reciprocatingframe 72 which moves 1n-a cam groove 70 on the frame,

. Amovement being imparted through connecting 'od73farms 74 and 7 6pivoted at 75,v

and nnecting rod'77 secured to crank 78 on the main shaft 34. Suction issupplied :to the mechanism by a pump 100, operated plate 32 having formfrom shaft 34. Valves 114 and 113, controlling the' suction supply tothe apron and thf` fingers respectively, are' operated lfrom cam shaftthrough the medium of cams 122..

The alm'ng mechanism-Upon passing into chute 92 the sheet falls to thelower end thereof and rests .upon pins which are set in the.ilnpression'cylinder and which are at rest in the position shown inFig..

Chute 92 is formed on one'side by a. solid Figi 13. The member which isupon the left in Fig. 5is provided with the alining -mechanism`136 whilethe member-137 upon the rightA in that figure is not provided with thealining mechanism but consists mainly of curved vwalls 138 and a lateralwall 139. This lateral Wall 13.9 of member 137 forms the gage againstwhich 'the sheets Vare moved by mechanism 136. The alining mechanismconsists of a pivoted arm 140 mounted on bracket 141 vby which member135 is secured'on rods 134, the lower end of this arm carrying portion142 of lateral wall 139. A spring 143 tends to hold portion 142 inits.normal position but a cam 144 on cam shaft 120 engages a roller 145 toprevent the inward movement of the lower 'end of the varm except whencut away portion.146of reaches the rollerat .the time when the sheet ofpaper is standing in the lowerend 'of the chute, and portion 142 of thelateral 1111.139 of member 135 then contacts with the edge of the paperand forces the paper against member137.` By this means the sheet isperfectly registered in both directions and is then ready to be takenonto the cylinder.

The cylinder mechanism .-long each `side of. bed plate 32 a rack 150'isplaced, this rack being. so designed that its pitch line comes in thesame plane as the faces ot' the type on the, bed plate. Each of theseracks meshesl with a sector 151 loosely mountedabout hub 152 ofimpression cylinder 153. -By the'reciprocation of the bed platethe'sectors are continually oscillated through a half revolution.Cylinder 153 is loosely n'iountedon a shaft 154 which' ex-l tends acrossthe frame.

Ou one of its hubs 152 outside of the sector thereon a disk 155 is,rigidlysecured, :this disk beine provided with'two V-shaped notches 151iarranged 4dialnetrically opposite each other. MountedllO on an extension157 of the main trame is a detent 158 whose spring pressed plunger 152)is ada ted to enter the notches in the, periphery o disk 155 and tothereby resilienlly and yieldix'lgly stop the diskandthe cylinder at theexact position desired without nndue shock. Thedisk is so set on thecylinder that the cylinder-is stopped in the exact position shown. inFigs. 4 and 6, while the spring is so set behind `the plunger thatit maybe forced out of the notch at the beginf end of cylinder 153. I The endsof the cylin der are each provided with two apertures 1(52 which arearranged'diametrically opposite each other and 1n the path which 1sAtraversed bypins 1GO so `that the pins will pressed intothe aperturesbv normally be n springs 191. This action normally takes place each timethe bed plate'reaches the upper end of its travel with the sectors inthe position shown in Fig. G. Upon the downward movement of the bedplate the sectors and the cylinder' are rotated in the directionindicated by the arrow until nearly a halfrevolution is completed. Justbefore the half revolution is completed the cylinder.

is released from'the sectors and isthen carrie'd on by its own momentumuntil plunger, 159 enters notch 156 andthus stops the cylremoved fromits last position. The disengagement .ofpins 160 from' the cylinder isaccomplished .up over these wedges and the pins arethere.- by movedoutwardly. This, action takes place at the time. above noted, thecylinder Dassin0-` on b its own momentum toits )osin .Y

. `tion of rest so that when the sector moves V the 4 cylinder is backto its original position the pins will not engagewiththe apertures inthe cylinder. The cylinder is thusleft in its final position whilethe-sector moves back to its Vinitial position'.l- .t i

operation of the machine moved as above described upon each downwardmovement ofthe bed plate. Means are providedhowever foral- In thelnormal lowing the bed plate to reciprocate without: d

. the movement of the cylinder. This means is comprised in a'l smallshaft 180 extending across the frame abovethe cylinder, this shafthaving arms 181 thereon which are connected to depending fingers 182.These fingers are formedvas is shown in Fig. 9 and their lowerdiagonalends are so placed that by a. rotation \of shaft 180 they thrown intoengag ment with heads 1 71of pins 160 when vthe pins are in the positionshown in Fig. 3. Thus by rotating shaft 189 by handle 183 in the properdirection the lingers are thrown into such a position that v the pinsride up on 'them and are thus prepressed lbefore referred to, arelocated.

by meansi of wedges 170l Vmounted on'extension-l. In the course oftheir'rotation heads 171 of the pins ride may be* vented from makingconnection with the apertures: in the cylinder. Thus the sectors may beallowed to move without moving the cylinder. y l

Referring particularly to Fig. 6 it will be seen that'portions of thecylinder surface are cut away, only about two'opposite quarters 190remaining. Over these portions provision 191 is made for stretching astiff backing -sheet 192 for the support of the sheets t-o be printedupon. Atl one edge of each of the cylindrical surfaces pins 130, Vi'thinthe cylinder two longitudinal shafts 193 are placed and a series ofspring fingers 194 on each of the shafts presses against one edge ofeach of the cylindrical faces of the cylin der between the pins 130. Aspring 195 connected to each of the shafts provides means for holdingthe 4lingers 'tightly against the l cylinder.

As before stated, the cylinder is loosely mounted on shaft 154. none'end of this shaft an arm 196 is mounted, a rod 197 being secured tothe arm. This rod extends.

along the side of the press as is shown in 1g.,3 and is provided on itsend with a block `198 which is adapted to engage with the .upper end ofbed plate 32 at the upper extremityof its motion, so that the shaft andthe attached parts are held in the position shown in Fig. G while thebedis-in its extreme upper position'. A spring 199 holds rod 197 andshaft 154 normally in a position rotated ,in the direction indicated bythe arrow in Fig. 6 from the position shown in that figure. Mounted onshaft 154 is a disk 200 carrying pins 201 and 202 on its periphery. .Atall times when `the cylinder is stationary and except when the bed is atits upper position, as-shown in Fig. 6, these pins stand under arms 203which are secured on Shafts 193. Shafts 193 are thereby held in suchaposition that fingers 194 are moved outwardly from engagement with thesurface of the cylinder and are in a position to receive a. sheetbetween them and the cylinder or torelease a sheet from that position.The position for the fingers which are taking the sheet is shown in Fig. 12, the sheet ropping down chute 92 onto pins 130 in-l side offingers 194. It will be seen that the pins 130 pass into slots in theends of lingers 205, these fingers preventing the sheet from sliding olfthe ends of the pins. Fingers 194 are moved outwardly between fingers205. J ust as the'b'ed plate reaches its upper position, shaft 154 isrotated froin its normal position to -the'position shown in Fig. 6 andfingers 194 are thereby allowed to press against the edge of the sheetresting on thel pins 130 and the sheet is thereby rnily held on thecylinder to be carriedharound with it. On the downward motion of the bedshaft 154 is carried again `to its normal iso . hang from4 a stationarysupport 207.

position, but in the meantime the cylinder he apertures in the cylinder,the wedges behas started torotate, so that arms 203 areging so locatedthat the pins are disengaged carried away from pins 201 and 202 andarenot engaged by them to again lift fingers.

194. To keep the rear' portion of the sheet up against the cylinderinthe movement thereof, long fingers Q06 are provided which The halfrevolution of the cylinder carries the sheet, which has been printed byimpression upon` the type in the form boX, to a. position opposite thatfrom which it started. When in this position arms 203 ride upover pins202 and fingers 194 releasethe sheet to Afall onto a set of belts 210which are continuously driven in the direction indicated by the ar- 'rowthrough the medium of gear and belt f collection boX 214k at the lowerIend of the machine.
